The occlusion perfusion catheter (OPC) universal drug delivery catheter. (a) The OPC, a multi‐lumen balloon catheter, is designed to temporarily occlude the target lesion from blood flow, flush the blood from the treatment chamber, and then locally deliver the therapeutic agents into the artery. A built‐in fiber optic pressure sensor continuously monitors the treatment chamber during delivery. (b) The distal end of the OPC catheter demonstrating the space occupying balloon, outflow port and distal occlusion balloon. (c) A cross‐section of the catheter showing the 5 lm that correspond to 1—proximal and distal balloons, 2—space occupying balloons, 3—inflow port, 4—outflow port, and 5—guidewire
